1. Watch your use of social media. Some people put everything on Facebook, from what they ate to how they did their hair today. Remember that the more information you give out, the more someone else will know your schedule and can figure out when you’re most vulnerable.
2. Safety in cyberspace. Although the Internet is educational and entertaining, it can also be full of danger if one isn’t careful. When communicating on-line, use a nickname and always keep personal information such as home address and phone number confidential. Instruct family members to do the same.
3. Don't check-in on Facebook or Foursquare when you arrive somewhere. Instead, check in as you leave. This way no one will be able to digitally stalk you and know your every move or when you're not home.
4. Along the same lines, avoid tweeting or Facebooking from vacation, especially if your account is public, as it's a way of letting the world know that your home is unoccupied.
